elastic component 4 abuts against the lower cover 5. The elastic
component 4 is retractable within the upper cover 2, thereby
driving the smoking pipe 1 to be extended out of the upper cover 2
or retracted within the upper cover 2.
[0027] The smoking pipe 1 has a step-shaped structure, including a
main body portion 10, a fitting portion 11 extended downward from
the main body portion 10, and a smoking channel 12 extending
through the main body portion 10 and the fitting portion 11. The
cross-sectional area in the radial direction of the main body
portion 10 is larger than that of the fitting portion 11. The
fitting portion 11 is receivable by the fastener 3. The bottom of
the smoking pipe 1 defines a receiving hole 15, and the top of the
receiving hole 15 is provided with a top wall 14.
[0028] The upper cover 2 has a hollow structure, including an upper
cover body 21, a step portion 22 extending upward from the upper
cover body 21, and a receiving cavity 20 passing through the upper
cover body 21 and the step portion 22. The cross-sectional area in
the radial direction of the step portion 22 is larger than that of
the upper cover body 21, thus the step portion 22 and the upper
cover body 21 are combined to form a step-shaped structure. The
upper cover body 21 has a protruding part 24 inwardly extending
from the inner surface of the lower end thereof. The protruding
part 24 has a protruding inner wall 25. The upper cover 2 further
includes a boss 23 protruding inward from the protruding inner wall
25.
[0029] The fastener 3 is sleeved on the fitting portion 11 of the

from the upper protruding part 330. Each lower clamping component
34 includes a lower protruding part 340 protruding downward from
the lower surface 32 and a lower clamping part 341 protruding
outward from the lower protruding part 340. The fastener body 30
has an outer surface and an inner face, both sides of the upper
protruding part 330 and the upper clamping part 331 are inwardly
slanted along a direction of the outer surface to the inner face of
the fastener body 30, and both sides of the lower protruding part
340 and the lower clamping part 341 are inwardly slanted along the
direction of the outer surface to the inner face of the fastener
body 30. The upper clamping components 33 and the lower clamping
components 34 are arranged in a staggered manner in the axial
direction, that is, the upper clamping components 33 and the lower
clamping components 34 are staggered along the top to bottom
direction of the fastener 3. Alternatively, the upper clamping
components 33 and the lower clamping components 34 can be aligned
in the axial direction. That is, the upper clamping components 33
and the lower clamping components 34 are symmetrically arranged
along the radial direction of the fastener 3. In this embodiment,
the number of the upper clamping components 33 is equal to the
number of the lower clamping components 34, which may be one, two,
three, and so forth. And the upper clamping components 33 and the
lower clamping components 34 may be provided in pairs, that is, the
upper clamping component 33 and the lower clamping component 34 can
be provided in various manners so long as the function of the
clamping can be achieved. The upper clamping components 33 are
spaced apart from each other to define a gap, and arranged parallel
to the axial direction of the smoking pipe 1. The lower clamping
components 34 are also spaced apart from each other to define a
gap, and arranged parallel to the axial direction of the smoking
pipe 1. The upper clamping components 33 can be evenly spaced. The
lower clamping components 34 can be also evenly spaced. The gap
between adjacent upper clamping components 33 is equal to the gap
between adjacent lower clamping components 34. Alternatively, the
number of the upper clamping components 33 can be different from
the number of the lower clamping components 34. Alternatively, the
gap between adjacent upper clamping components 33 can be different
from the gap between adjacent lower clamping components 34.
[0030] The lower cover 5 is of a concave shape, including a bottom
50, an extending wall 51 extending upward from the circumference of
the bottom 50, and a receiving space 54 enclosed by the bottom 50
and the extending wall 51. The center of the bottom 50 defines a
through-hole 52 passing through the bottom 50. The bottom 50
further includes a bottom wall 53 facing the elastic component 4.
The top end of the elastic component 4 abuts against the top wall
14 and the bottom end abuts against the bottom wall 53. The elastic
component 4 may be a spring or an elastomer with elasticity. The
elastic component 4 is housed inside the receiving space 54 and the
receiving hole 15 when the elastic component 4 is compressed, and
the elastic component 4 is housed inside the receiving space 54,
the receiving hole 15 and the receiving cavity 20 when the elastic
component 4 is extended. There is a gap 13 between the outer
surface of the main body portion 10 of the smoking pipe 1 and the
inner surface of the upper part of the receiving cavity 20, and
there is a gap between the outer surface of the fastener body 30 of
the fastener 3 and the protruding inner wall 25, so as to
facilitating the extending and retracting of the smoking pipe
within the receiving cavity 20.
[0031] The smoking pipe 1 can be extended out of the upper cover 2
and retracted within thereof. In one embodiment, when the smoking
pipe 1 is in the retracted state, the fastener 3 is affixed to the
fitting portion 11 of the smoking pipe 1, and the smoking pipe 1 is
housed inside the receiving cavity 20. At this time, the elastic
component 4 is in a compressed state, and the upper clamping parts
331 of the upper clamping components 33 abut against the boss 23,
so that the smoking pipe 1 cannot be pushed out by the elastic
force of the elastic component 4. When the smoking pipe 1 is
required to be extended, the smoking pipe 1 is pressed so that the
upper clamping parts 331 are separated from the boss 23, and the
smoking pipe 1 is pushed out with the elastic force of the elastic
component 4. At this time, the lower clamping parts 341 are engaged
with the boss 23 so that the smoking pipe 1 is restricted from
being further extended outward. Then, when the smoking pipe 1 that
has been pushed out is pressed inward, the upper clamping parts 331
may deform elastically and move over the boss 23, and then abuts
against the boss 23, thereby the smoking pipe 1 comes back to the
retracted state. The upper clamping parts 331 can be made of
elastic material. The upper clamping components 33 and the lower
clamping components 34 are arranged in an alignment manner in the
axial direction. That is, the upper clamping components 33 and the
lower clamping components 34 are symmetrically arranged along the
radial direction of the fastener 3. Therefore, the boss 23 can
abuts against the upper clamping components 33 or engage with the
lower clamping components 34, when the fastener 3 and the smoking
pipe 1 are moved relatively along the axis of smoking pipe 1 under
the pressing action. It will be appreciated that the boss 23 can be
provided on the protruding inner wall 25 in a circumferential
direction. So that the boss 23 can cooperate with the upper
clamping components 33 or the lower clamping components 34 under
the pressing action to restrict the movement of the smoking pipe 1,
regardless of whether the upper clamping components 33 and the
lower clamping components 34 are symmetrically arranged along the
radial direction of the fastener 3 or staggered along an up to down
direction of the fastener 3.
[0032] In another embodiment, the extending and retracting of the
retractable mouthpiece 100 may also be achieved by rotating and/or
pressing the smoking pipe 1. For example, if the smoking pipe 1 is
rotated so that the upper clamping parts 331 are separated from the
boss 23, the smoking pipe 1 is pushed out for a certain distance
with the elastic force of the elastic component 4, while the boss
23 comes to engage with the lower clamping parts 341, thus
preventing the smoking pipe 1 from being further extended outward.
At this time, the retractable mouthpiece 100 is in the extended
state. When the smoking pipe 1 that has been pushed out is pressed
inwardly in a certain distance and then rotated in a certain angle,
the upper clamping parts 331 cooperate with the boss 23, and
thereby the smoking pipe 1 comes back to the retracted state. The
upper clamping parts 331 cooperating with the boss 23 in such a
manner that the upper clamping parts 331 engage with the boss 23,
or the upper clamping parts 331 abut against the boss 23. The upper
clamping components 33 and the lower clamping components 34 are
provided in a staggered manner. It will be appreciated that the
protruding inner wall 25 can be further provided with a guide
groove (not shown), and the lower clamping parts 341 can move along
the guide groove. The cooperation of the lower clamping parts 341
and the guide groove can guide the user operation of rotating and
pressing the smoking pipe 1. That is, in the process which the
smoking pipe 1 is extended out of the upper cover 2 or retracted
within thereof, the movement path of the smoking pipe 1 coincides
with the movement path of the lower clamping parts 341 along the
guide groove.
[0033] In the above two embodiments, the upper cover 2 and/or the
smoking pipe 1 are provided with an indicator indicating a position
to be rotated or pressed.
[0034] The present disclosure further provides an electronic
cigarette with the above-mentioned retractable mouthpiece 100.
[0035] For the retractable mouthpiece 100 and the electronic
cigarette having the same, the upper clamping components 33 or the
lower clamping components 34 of the fastener 3 in the retractable
mouthpiece 100 can be cooperated with the boss 23 of the upper
cover 2 when the smoking pipe 1 is pressed and/or rotated, and the
smoking pipe 1 can be extended out of or retracted into the
receiving cavity 20 by the elastic force of the elastic component,
so that the smoking pipe 1 can be prevented from being frequently
exposed and subjected to external pollution, and it is thus both
healthy and convenient. The above are preferred embodiments of the
present disclosure described in detail, and should not be deemed as
limitations to the scope of the present disclosure. It should be
noted that variations and improvements will become apparent to
those skilled in the art to which the present disclosure pertains
without departing from its spirit and scope. Therefore, the scope
of the present disclosure is defined by the appended claims.
